Adjustable bar stool



FIG. 1 is a perspective view of an adjustable bar stool showing my new design; and,

FIG. 2 is a top plan view thereof.

A bottom plan view is omitted since the bottom plan view is invisible in normal use.

Dashed lines shown on the surface of the adjustable bar stool are understood to represent stitching.

The dot-dash lines depict portions of the adjustable bar stool which the design is embodied that form no part of the claimed design. 

CLAIM The ornamental design for an adjustable bar stool, as shown and described.
